Configuration at C-24 of 24-methyl and 24-ethylcholesterol in tracheophytes

  • Published:
Lipids

Abstract

24-Ethylcholesterol was shown by proton magnetic resonance spectroscopy to have only the α-configuration in a series of tracheophytes ranging through the evolutionary hierarchy from ferns through gymnosperms and primitive angiosperms to climax angiosperms. 24-Methylcholesterol, however, was consistently an epimeric mixture, with the 24α-epimer present in about twice the concentration of the 24β-epimer. 24-Methylcholesterol was always present in smaller amount than the 24-ethylcholesterol.
